RODIN, or EAST CLEVELAND, onto 1 VENTILATING AIVPARATUS Application filed February 5, 1930. Serial No. 425,999.

This invention relates to a ventilating apparatusadapted for use in connection with garages and especially large garages where a great deal of work is necessarily done with 5 motors running; and the principal object is to provide an improved means for disposing of exhaust gases whereby theair is kept free from-injurious or poisonous materials, especially carbon monoxide.

l A further object is to provide amechanism of this character which shall beextreinely convenient in use and avoid the necessity of having a plurality of pipes depending from various points in the garage when the same ,5 are not in use. r p

A further object isto provide an apparatus of this character which shall be con structed in sections which may be conveniently shipped and which will be adapted .2 for installation in various types oflayouts merely by assembling certain standard units in different patterns. 7 f

A further object is to provide a roof ventilator attachment to extend above the garage and which isprovided with auxiliary draft producing means adapted to assist in the eduction fgases from the interior of the garage. I I V l Other objects will appeanfrom the followd ing description.

Referring to the accompanying drawings, Fig. 1 is a schematic layout showing an illustrative embodiment ofmyginvention and the manner of using the same; Fig.2 is a secing-outlets which I employ; Fig. 3 is a.sectional view at rightangles to theview of Fig.2; Fig.- 1 isa partial sectional view corresponding to the view of Fig. 2 and showt ing the gas eduction pipe in attached position, together with the attaching means which I employ; and Fig. 5 isa detail view of a portion of the attaching means, In Fig. 1 the numeral represents the roof ofa garage. Mounted on the roof 1 0 many suitable manner and extending therethrough is a pipe ll upon which is rotatably mounted the ventilator 12. This ventilator is of larger sizethan the pipe 12 and allows the upward assistlin the production of a draft through i said pipe. Attached to the rooflO by any suitable hangers 13 are pipes 14 and 15. connected with thepipe 11. and runningtovarious partsof the garage.' These pipes'are made in sections, asshown, and it .IS evident that they may be arranged nearthe roof in; any suitable layout so as to provide outlets at all points necessary for convenience.

The outlets are illustrated schematically in Fig. Lat 16 and are of thev construction shownin Figs. 2 and 3. :Alfiexiblepipe 17is adapted for attachment. to theoutlet 16 and may be connected at one end to any such outlet, and at the other end to the exhaust'pipe of an automobile. When the pipe 17 is not needed,

the samecan be conveniently hung on the V V wall oiithegaragewhere it will not bea nuisance, as would be the case if it were permanently attachedto the outlet. 3 Each outlet 16 is constructed in accordance with theshowing of Figs. 2 and 3. The tube V 18 is connected, as shown, to the pipel5 and extends forv a: short .jdi'stance? thereinto. Mounted. onthe inner end of sa-idpipe by'a. bolt 19 is a spring member 20.attached:at'its other end to a valve 21." .1 Pivoted inIthe pipe "l8 and rigidly attached tothe valve21 isa V- shaped rod 22. 'Mountedon a bracket 23 at the other end of the pipe 18 is a control member'24 which is adapted to swing through a slot 25 in the pipe 18.' vTheoutward swing ofthe'member 24 is-limited by means of an outwardly strucktongue 26 which engages with the wall ofpipe 18 adjacent the slot 25.

This construction is rendered'necessary by reason of the fact that if the outlets 16.not in use were open, there would be insufficient suction through the pipe 17 to deliver the exhaustgases or the resistance would the so great that the pressure at which the gases exthe muffler would be insufficient to carry the same'readily through. to outer atmosphere. It might even result in dischargeof-the same downwardly through the other. openings in stead of securing the desired exhaustionto outside Thetubefl'rlis-of well known flexible con- -lstruction and is adapted to be slipped over ,ha-ust intothe atmosphere orexhausted from I vided with an eye 33 and a link'34aextendinga through such eye and connects the same with the member 31 at the bend thereof. 'When this construction is employed, after pushing the pipe 17 over the lower end of the outlet, the hook 30 is caught over'the top of the pipe 15 and the bifurcated. portion 32' pushed over the pipe17, while the handle 31 is held'at an angle thereto so thatth'e outer portions of the bifurcated members extend downwardly; In this position the member 32 is pushed into frictional or binding contact with the pipe 17 and then the handle 31 is pulled downwardly, which results in a tightening and a suspension of the pipe 17 by means .ofthe hook.30. The handle is employed to lift and/or guide the flexible tube into position onthe'outlet.

Itwill be evident from the foregoing that I have provided a simple and convenient device fordisposing of exhaust gases, and while I have illustrated one embodiment of my invention, I wish it understood that I am limited only in accordance with. the appended claims; Having thus described my invention, what Iclaimis:
